Can a nebula form from a supernova?

The ejected envelope expands away from the central star and creates the nebula that we see. So, if you look at the pictures of classic planetary nebulae like the Ring nebula, you will be a ring of material with a star in the center. The ring of ... The exploded remains of the star form a "supernova remnant". read more

Over millions of years, supernova remnants can cool and condense enough to form “giant molecular clouds,” collapsing into “HII regions” where baby stars are born. The nebulae formed by exploding stars contribute directly to the elemental enrichment of our universe and are critical to the continued evolution of the cosmos. read more

A supernova remnant (SNR) is the structure resulting from the explosion of a star in a supernova. The supernova remnant is bounded by an expanding shock wave, and consists of ejected material expanding from the explosion, and the interstellar material it sweeps up and shocks along the way. read more

For decades, scientists have suspected a star explosion called a supernova helped trigger our solar system's formation. In particular, the shock wave from the explosion is thought to have compressed parts of the nebula, causing these regions to collapse. read more
